GAS-WASHER.

SPECIFICATION forming part of Letters Patent N 0. 677,865, dated July 9, 1901.

Application filed SeptemberZO, 1900. Serial No. 30,565. (No model.)

To all whom it may concern:

Be it known that I, OLAF N. GULDLIN, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Gas-Washers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for washing and purifying gas.

One object of myinvent-ion is to provide for more thoroughly and uniformly dividiug'gas into fine streams and subjecting it'to the ac= tion of washing-water or ammoniacal liquor to remove various impurities, such as carbonaceous matter, ammonia, carbonic acid, and

sulfurcompounds.

A more specific object is to provide means for readily detaching and removing the perforated plates, or frames comprising such plates, used in dividing gas into fine streams from the washing-box for repair or renewal of parts without taking the box to pieces.

The matter constituting myinvention heroin will be defined in the claims.

I will now describe the details of construction of my improved washing apparatus by reference to the accompanying drawings, in which-' Figure 1' represents a vertical longitudinal section through the washing-box at the gas inlet on line m 93, Fig. 2, the middle portion being broken away. Fig. 2 represents a vertical transverse section thereof on the line of the gas-outlet. Fig. 3 represents a vertical longitudinal section through a portion'of a gas-inlet channel. Fig. 4 represents an end view looking toward the deflecting-apron and into part of the gas-inlet channels.

The gas-washer box A is constructed of metal plates bolted together by their flanges in a well-known manner. One end of the box is provided with an inlet gas-opening a, where the gas-supply pipe is bolted to the plate. The gas-outlet opening a. is preferably made in oneof the sides of the box, to which the outlet-pipe will be bolted. The deflectingapron B is bolted to the inwardly-projecting flange a extending across one end of the box above the inlet a and down the sides of the box, as shown in Figs. 1 and'2. This apron extends downward across one end of the box to the normal water-line and has bolted to its lower edge the an gle-iron b for making a tight joint with the detachable frame D below the same. The lower end of apron Bis made with a number'of deep notches b, Fig. 4E, corresponding to the number of inverted gas-channels O. The gas-channels O are in the nature of inverted troughs open'at the bottom and are provided at their inlet ends'with flanges by means of which they are bolted to the apron B around the notches b, Fig. 4. The rear ends of these channels are closed and bolted to the transverse angle-iron c, which is bolted to the inwardly-projecting flange a for properly supporting the channels. The channels are made with thickened lower edges having flat surfaces 0 for making tight joints with the detachable frames D, which carry the perforated extension-plates, as shown in Fig. 2.

The gas-channels at the sides of the box are made of the plates 0, each having at the top a flange c, which is bolted to the side plate of the box, as shown in Fig. 2.

-My perforatedplates for dividing the gas into numerous small streams are preferably made detachable from the gas-channels O and are so supported and arranged that they can be readily removed through the manhole X in one end of the box, so that they may be readily repaired when worn or defective and then replaced.

The side and top perforated plates'are preferably secured together in a frame D, and thewhole frame may be detached and re moved together. The frame D is constructed of the parallel angle-irons d, the closed end plate at at the inlet end, the closed end plate d at the outlet end, and the transverse bracebars (P. To the angle-irons and end plates are secured the downwardly and inwardly inclined perforated extension-plates g, which are preferably provided with outwardly-bent fiangesiat their lower edges for giving them greater strength. A perforated crown-plate h is also secured to the angle-irons d and is preferably arched or crowned and more finely perforated than the side plates 9.

The entire frame D, carrying the perforated side plates and the crown-plate, may be a permanent extension of the gas-channels C, but is preferably made detachable, so that it may be readily removed from the box, which may be arranged as shown in Figs. 1 and 2 when frame D is clamped in position against the lower edges 0 of the channels 0 by means of the clamping hangers K and suitable connections. Eyebolts f, having screw-threaded lower ends, are passed through openings in the cross-bars d and secured by nuts, as shown. Between the bars d and the perforated crown-plate h are placed the spacing-sleeves e, which bear against plate It and which in turn bears against flanges of the bolts f. The bolts fare provided at their upper ends with eyes, as shown, for engagement with the hooks 7c of clamping-rods K. The rods K have screw-threaded upper ends 76, which pass through screw-threaded openings in the supporting-bars L. The bars L rest at their outer ends on shoulders c at the tops of channels 0, as clearly shown in Fig. 2. Asimilar construction holding the frame D in position against the channels 0 by sup ports from the bottom of the box A may be used. The clamping-hangers K, being socured to the bars L by nuts, may be readily detached therefrom by unscrewingthe upper nuts, and thus lowered to the bottom of the box for removal through the manhole X. By loosening the upper nuts above bar L the books it may be disengaged from the eyebolts f, thus freeing the frames for removal. With regard to the walls of the channels 0 it is to be noted that the perforated extension-plates gare inclined downward and outward toward the spaces between the channels, so that bubbles of gas after passing through such plates will rise through the water entirely free from the plates instead of following alongadjacent to the plates, as they wouldif the latter were vertical. More effective washing action is secured by causing the bubbles of gas to pass monia liquor extends along the inlet end of the box and connects by branch pipes m, through the apron B, with the spaces between the channel 0 above the perforatedcrownplate h. The discharge pipe or passage N for liquor extends downward from the rear end of the frames D into the lower compartment I of the box, as shown in Fig. 1. The discharge pipe or passage N is preferably made a part of the rear end plate d of the frame D, and is provided at its upper outer edge with a flange, which fits up against the angle-iron c.

The outlet-pipe P for liquor connects with the bottom of the box at the gas-inlet end thereof, and is in practice provided on the outside of the box with an adjustable overflow (not herein shown) of any suitable construction. The series of longitudinal gaschannels 0 and the intermediate perforated crown-plates h divide the box into an upper compartment H and a lower compartment I. The gas passes off from the upper compartment H through the outlet a, which is guarded by an inclined apron E, as shown in Fig. 2.

One or more manholes X, covered by a plate X, is preferably provided at each end of the box, as shown in Fig. 1. One or more sight-openings to may be provided in the side wall of the box and covered by a glass plate a, secured in a suitable frame for observing the liquor level.

The normal water-line when no gas is passing is indicated at V, Fig. 2, just at the lower edges of the channel 0, the level being uniform at the bottoms of the channels. When a medium volume of gas is being passed through the inlet-channels C, it forces the water or liquor down below the channels, through the perforated plate g, and up into the space between the plates and also into the space above the crown-plate h, as indicated at W in Fig. 2, and the gas then passes through the perforations and up through the displaced water or liquor, then through the crown-plate, and off through the spaces between the channels 0 to the outletpipe. In practice it is found that a clear gasspace is maintained below the archedplates h, as shown in part marked V. While gas is passing through the channels and perforated extension-plates, water or ammonia liquor is fed through the branch pipes m, above the crown-plates h, and, owing to the pressu re of gas below, gradually flows along over the perforations in the tops of such plates to the discharge-pipe N, and thence down into the lower compartment I of the box. The gas, therefore, in passing through the perforations in the crown-plates his compelled to pass up through a layer of fresh inflowing liquor. When a larger volume of gas and nearly the maximum amount which can be passed is admitted through the channels, it will still further depress the surface of the liquor below the channels and cause it to rise higher above the crown-plates h, as indicated at Y in Fig. 2? Although a larger volume of gas is passing and will therefore flow more rapidly the streams of gas passing through the extension-plates Q will be subjected to a greater depth of liquor, so that: the washing and purifying action will be maintained substantially uniform in time contact, as illustrated in the part marked Y.

My extension-plates 9 will be effective and give valuable results without the crownplates h, and the crown-plates h will also perform a useful function by themselves; but I preferably use both combined in a detachable frame 'D, as above described and as shown in the drawings, as giving the most satisfactory results. My invention, however, is not confined to the use of both the extension-plates g and the crown-plates h, nor to the detachable method of construction, as either or both may form permanent parts of gas-channels c.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
